libglusterfsclient: Add dirent pre-fetching and caching

The fop interface is such that we're able to extract more than
1 dirent in a readdir fop. This commit now enables libglusterfsclient
to read multiple entries on a glusterfs_readdir call. Once these
have been pre-fetched, they're cached till either glusterfs_closedir
,glusterfs_rewinddir or glusterfs_seekdir are called.
The current implementation is beneficial for sequential directory
reading and probably indifferent to applications that do a lot of seekdir
and rewinddir after opening the directory. This is because
both these calls result in dirent cache invalidation.
